Celeborn has never donned a suit of armor in the movies, and to the best of my knowledge, the novels. But that being said I am sure he owns a suit of armor somewhere in his elven kingdom which he uses only in the direst emergency, so I made this minifig based on a picture I found on the internet somewhere, but can't seem to be able to re-locate since.

I especially like the fact that this armor matches Elrond's and Gil-Galad's in design, but comes in silverish hue.
